Toallwhomit mag concern;

1 Be itknown that. I, WILLIAM H. Homes, a citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented new and useful Improvements in Glass-Delivering Apparatus, of which'the following is a specification.

This invention relates to apparatus for delivering charges of molten glass from a furnace outlet or other source of supply to" a plurality of molds or to different sets or seriesof molds. One object is to provide for-the delivery of mold charges to the'molds j while the latter are moving, thereby en-' abling the mold carrying tables to be constantlyrotated instead of stopping to receive each successive charge. A further ob-' ject is to provide, in combination with suitable charge forming and feeding apparatus anda plurality of molds or sets of molds, improved means for selectively. transferring and delivering the charges from the feeding apparatus to the molds or to any. preferred type of glass shaping machines.

An important feature of the present invention is the provision 'of an inclined trough-or transfer member extending from beneath a furnace outlet or charge forming device and having a plurality of outlets through which the charges may be selectively delivered tomolds at different receiving stations, by manipulation or movement of the transfer member.

Thetrough may be varied in shape or design to a considerable extent, so long as by manipulation or movement of the same, it is capable of delivering to molds at different receiving stations, and for this purpose it is preferably provided with a plurality of outlets through which the charges the tables may be intermittently rotated if desired. The trough is mounted for oscillation upon aninclined axis extending long-itudin'ally thereof, so that the trough outlets may swing in a path located in a plane on line 6 6 of Fig.4.

extending at an angle toflthe horizontal,

whereby the lowered end is brought into delivering relation with the traveling mold. "The swinging movement of thedelivering end of the trough-on itsinclined axis-causes itto move in a curvedpathwhich approximately conforms to the'curved path or'orbit of travel of the mold, as viewed from above,- so as to allow for variations which are, liable to occur" in the time'of delivery, the posi tion of the deliveringend ofthetrough being suitable for directing the glass in, its proper trajectory to the mold, even when the delivery-is early or late.

One embodiment of the invention 7 is illustrated in the accompanying drawings, .in which Figure 1 is a plan showing the trough mo d adapted for deliveryltotwo different carrying tables. 3 y

In'the present embodiment of the invention, 10 represents the forehearth of a furnace or molten glass container having a discharge outlet 11 and an implement 12 for controlling the discharge of the gobs or mold charges 13, which may be severed by any suitable means, such as the shear blades 14, actuated by any well-knownshear mechanism. The mold charges 13, when severed,

(lI'OP by ravity into the upper end, f the V inclined trough or transfer member 15, which is wide enough at its receiving point to insure the proper entrance of-the charges therein. At its lower end the'trough is provided with a plurality of outlets, from which the charges are discharged atan angle to the body of the trough, the; outlets being preferably in the form of branching channels 16 and 17, although they are not necessarily limited to this form of construction. The branches 16 and 17 merge smoothly into the body of the trough so that the charges will be directed into whichever channel is in lowered'position at the time the charge reaches the point where the trough divides. The body and branches of the trough are substantially of uniform size and contour, and of such shape as will best maintain the charges in their original form as delivered from the charge producing apparatus. As shown in Figs. 1 to 3 inclusive, the branch 16 is in lowered position for delivering toone of the molds of the right-hand series 18 while the opposite branch 17, for delivering to the molds of the left-hand series 19, is in raised position, thereby directing the charge into the lowered channel.

The tables 2Q and 21, carrying the two sets or series of molds 18 and 19 respectively, are supported by suitable frames or standards 22 and are preferably geared together and driven by a gear 23 on a suitably driven shaft 2 1. However, the tables may be otherwise mounted and driven in any preferred manner, either continuously or intermittently. The trough may be oscillated in various ways best suited to the design or construction of the machines with which the device is employed, whereby the charges may be selectively delivered to different sets of molds. so that a greater number of charges may be successively delivered to one set of molds than to another, if preferred. In the present embodiment the trough is provided with truunions 25 and 26 journaled in the upper and lower brackets 27 and 28 (Fig. 3).

The trough is preferably made substantially semicircular in cross section and the axis 29 thereof, about which it is oscillated, passes approximately through the longitudinal center of the trough and through said bearings, although if desired the'axis may be at an angle to the body of the trough or may be inclined to any extent required for obtaining the desired curved movement of the delivering ends when delivering to molds which move in circular or curved paths. For delivering to molds which move in an approximately straight line, the axis may be horizontal. The axis preferably passes approximately through the center of that part of the trough which receives the charge, as it falls from the furnace outlet, so as to minimize the lateral movement of the sides of the trough at this point, whereby to insure the delivery of the charge to the trough when the latter is rocked to its extreme delivering positions. Any suitable means for rocking the trough may be employed. In the present instance, the trough is provided with a beveled gear sector 30 driven by a rack, or by a gear 31 fixed on a shaft 32 supported upon brackets 33 and 34:, the latter of which is extended upwardly to support the bracket 28 carrying the lower end of the trough.

Upon the shaft 32 is fixed an arm 35 having a roll 36 at its outer end, engaging a cam 37 on the bottom of the mold carrying table 20.. Also fixed on the shaft 32 is an arm 38, and a spring 39 connects the arm with the frame 22 or with any convenient support to retain the roll 36 in contact with the cam 37. Rotation of the table and the cam 37 effects oscillation of theshaft 32, which through the rack 31, oscillates the trough to cause the delivery of the charges to the different sets of molds. The cam for oscillating the trough may be mounted separately from the table, or be made in separate parts, or adjustably mounted on either table so that it may be adjusted forwardly or backwardly to vary the time of the swinging movement of the trough relative to the movement of the. rotating table. The cam may be provided with relatively long and short dwell periods to effect the delivery of a greater number of charges to one set of molds than to the other, if desired. The entire mechanism for moving the trough may, if desired, be separate from the tables and driven in proper timed relation with respect thereto.

In the modification shown in Figs. 7 and 8, the general construction is substantially the same as in the other views, the difference being that the trough consists of two sections, the upper section 40 being sup ported in fixed position upon a bracket a1, while the lower portion 42 is provided with a trunnion 13 journaled in a relatively long bearing 4 1, preferably carried by an extension on the bracket 34. The movable section 42 is oscillated in the same way and by the same means as in the preferred form of the apparatus, and is adapted to deliver to the different sets of molds precisely in the same manner as in the preferred form. The movable section 42 is adapted to at all times be in position to receive the descending charge 13 (Fig. 8) from the fixed section 10 of the trough, since the axis about which 1t is oscillated passes substantially through the centers of both sections. In this form it is not necessary to enlarge the upper end of the trough sertion' lO, since it is permanently fixed in receiving position and may, therefore, be made relatively narrow to correspond more nearly to the size of the charge.

The term selectively, as used in the specification and claims, means that the number of charges being delivered to the different sets of molds and the order of succession of such delivery may be varied to suit different conditions. In ordinary practice the trough would be oscillated to deloo changed by suitably modifying the cams, as

stated above, so that it will deliver any desired number of charges in succession to one table and thereafter deliver any desired number in succession to the other table, or delivery may be made in any other order found advisable. This feature will be of advantage in cases where it is desired to complete an order on the same machine at the same time for glassware of different shapes, sizes or weights and for different quantities of each.

The illustrated embodiment of the invention may be modified and changed to a considerable extent without departing from the scope of the invention as expressed in the claims.
